Sebennytos or Sebennytus (Greek: Σεβέννυτος, Ptol. iv. 5. § 50, Steph. B. s. v. or ἡ Σεβεννυτικὴ πόλις, Strabo xvii. p. 802) or Egyptian: Tjebnutjer (𓊹𓎀𓃀𓃘𓊖), (Arabic: سمنود, Samannud) was an ancient city of Lower Egypt, located on the Damietta (Sebennytic) branch of the Nile in the Delta. Sebennytos was the capital of Lower Egypt's twelfth nome (the Sebennyte nome). Sebennytos was also the seat of the Thirtieth Dynasty of Egypt.
Sebennytos lies nearly due east of Sais, in latitude 31° north. During the Thirthieth Dynasty and nearby, on the same banks of this branch of the Nile River, was Behbeit El Hagar. Sebennytos was anciently a place of some importance, and standing on a peninsula, between a lake (λίμνη Σεβεννυτική, now called Burlos) and the Nile, was favorably seated for trade and intercourse with Lower Egypt and Memphis. The neglect of the canals, however, and the elevation of the alluvial soil have nearly obliterated its site. 
Sebennytos is perhaps best known as the hometown of Manetho, a historian and chronicler from the Ptolemaic era, c. 3rd century BC. Sebennytos was also the hometown of Nectanebo II, and he was its last ruler.
A temple dedicated to the local god Onuris, or Onuris-Shu, and his lioness goddess mate Mehit, once existed at this location but is now reduced to ruins. A fragment to where kings would have made offerings to Onuris and his wife, is on display at the Walters Art Museum. The site is also known as part of the route of the Holy Family during their time in Egypt.
In 1843, Sir John Gardner Wilkinson described it as a place of some size, with the usual bazaars of the large towns of Egypt, and famous for its pottery, which are sent to Cairo. It is in latitude 30° 58' 45". Here are the mounds of Sebennytos, the city of Sem, Gem, or Gom, The Egyptian Hercules. In Coptic it is called Gemnouti, which implies "Gem of God," and shows the origin of the present as well as the orthography of the ancient name; and it is remarkable that the name of the god begins with the word noute in many legends.
